U usually sell when it is facing a stong resistance level going to the prevous chart, but usually if it broke the prevous resistance easily then expect it to hold the high price on the resistance next.

But the USD/JPY and EUR/JPY both have lost ground yesterday more than 200 pips because of the issue of Japan bank economic status when pushes all currencies against the Yen down esp the USD and EUR
So, i suggest to watch the historic support and resistance levels on the 4hour and daily charts since the hourly charts now are now behaving in the usual manner
Good luck
